CHECK FOR SHIPPING DAMAGE
Prior to leaving the factory, each cabinet is throughly inspected and
performance tested to assure proper operang temperatures.
Check the crate thoroughly for signs of shipping damage. If external
damage exists, internal damage is also probable. Uncrang should be done
while the carrier´s representave is present. Otherwise, the equipment
should be uncrated as soon as possible, preferably within ve (5) days.
The manufacturer is not responsible for in-transit damage and the
consignee must le any required damage claims directly with the carrier.
If the damage is severe and obvious, write a brief descripon of the evidence
on the carriers delivery receipt, and above the carrier representave’s
signature. Call the distributor or dealer immediately, indicang that the
cabinet was damaged.
If no obvious crate damage is present, within two hours of receiving the
cabinet from the carrier, remove the packaging to inspect for concealed
damage.
1. If concealed damage is found, call the carrier immediately, save all
crang materials, and le the necessary freight claim with the carrier.
Check for accesories: Check that the shelves are inside the refrigerator,
including the four clips or supports for each shelf.
11
HANDLING THE CABINET
1. Always move the unit in an upright posion. Do not set it on its side or upside
down as you may damage the cabinet and spill the compressor oil.
2. If liing the unit, hold it from its base. It is recommended to use a dolly.
3. Do not let the unit fall abruptly.
4. Place the cabinet on a surface solid enough to prevent vibraon and strong
enough to support the combined weight of the cabinet and the product load.
Quick guideline: Esmate 35 pounds per cubic foot of storage space.
5. Cabinets should never be placed in front of windows or glass doors where
sunlight will be in direct contact with the units. If a cabinet is located near
a window or glass door, provide an adequate shade to block the sun´s rays.
6. Ambient temperature must be between 60°F and 86°F. Low ambient
temperatures below 50° F are as harmful as high ambient temperatures.
Extreme temperatures will denitely aect the performance of the cabinet.
7. Failure to properly level the cabinet could hinder proper drainage and door
operaon. Leveling legs are provided with the cabinets. Level the cabinet by
using the adjustable poron of the leveling legs as needed.
8. Clearance: Leave a space of at least 8” between the back of the cabinet and
the wall to provide adequate air circulaon of the unit compartment.

1. Remove the external packaging (corrugated board and plastic
wrapping). Check for concealed damage. If any damage is idened,
immediately forward a complaint to the transportaon company.
2. Move the cooler the closest possible to its nal locaon, before
removing the skid.
3. Using a screwdriver remove the screws that x the skid to the cooler.
The base of the refrigerator has heavy duty leveling legs underneath so the
cabinet may be leveled appropriately and to allow room to clean beneath
the cabinet.
Level the cabinet front to back and side to side with a level by using the
adjustable poron of the leveling legs. This is vey important to insure proper
draining and door operaon.
13
To install casters:
Casters are supplied as oponal equipment. Only use genuine casters or the base
of the cooler might suer damages. When installing the casters it is important to
hand ghten securely against the base rail reinforcement assembly (see image). The
top edge of the caster must make rm contact with the reinforcement assembly.
Each unit requires a 110 Volt individual, properly grounded branch circuit
with a 3 prong grounding type receptacle, protected by a 15 or 20 Amp
circuit breaker or me-delay fuse.
Electrical installaon must be in accordance with Naonal Electrical Codes
and local ordinances.
